Kevin thinks it’s so much better to see a flush spreading from cheek to chest, eyelashes quivering when touched just right, the trail of hair to the promised land...

I love this sentence mostly because I generally prefer when actions and feelings are implied than described.

I have a question, though.

He grabs a corner of the bedspread and rolls on top of Kevin, successfully burritoing them in it.

Did you mean "burrowing" or it is an image and I just completely missed it and ruined its effect by asking you about it? In which case, all my apologies.

Great story, great writing, hope to read more from you soon. ;)
